Which of the following are assumptions regarding the kinetic theory of gases?
I. Gases are composed of discrete molecules.
II. Gas molecules are in random motion.
III. All collisions between molecules are elastic in nature.
IV. Temperature affects the molecular activity.

Question

Quizplus · Accepted Answer

All four statements are assumptions of the kinetic theory of gases. The first statement, I, is the starting point of the theory, which assumes that gases are composed of discrete molecules. The second statement, II, states that gas molecules are in random motion, which is a crucial assumption of the theory as it explains various gas properties. The third statement, III, presupposes that all collisions between molecules are elastic, and therefore no energy is lost in a collision. The fourth statement, IV, establishes that temperature affects the kinetic energy of gas molecules.
